cryptopilot-mcp CLAUDE.md

cryptopilot-mcp CLAUDE.md is an instructions file for coding agents from cryptopilot-tools/cryptopilot-mcp. It costs 1,640 tokens per session, scanned A, original, MIT.

A repository guide for AI coding agents working on CryptoPilot MCP, a read-only server that exposes cryptocurrency and brokerage portfolio data. It documents the project structure, technologies, authentication methods, and five MCP tools.

In plain words
What is it for?
For onboarding agents, explaining the TypeScript and Node.js stack, documenting Coinbase and SnapTrade integrations, and describing how portfolio data reaches MCP clients.
Why use it?
It gives an agent the project context and boundaries it needs before changing code, reducing incorrect assumptions about the system or related projects.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cryptopilot-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project

CryptoPilot MCP — A read-only Model Context Protocol (MCP) server that exposes crypto and brokerage portfolio data to Claude Desktop and other MCP-compatible clients.

Project boundary: CryptoPilot is a completely independent project. Agents working in this repository must not reference, compare, or assume any relationship with other projects (including stockpilot-mcp). Each project has its own scope, codebase, and decisions.


Stack

  • Language: TypeScript (strict mode)
  • Runtime: Node.js 18+
  • MCP SDK: @modelcontextprotocol/sdk v1.29+
  • Transport: stdio
  • Validation: Zod
  • Auth methods: JWT ES256 (Coinbase), HMAC SHA256 (SnapTrade)
  • Package manager: npm

Architecture

Claude Desktop communicates with the MCP server over stdio. The server uses an abstract BaseProvider class, with concrete implementations for Coinbase (direct Advanced Trade API) and SnapTrade (which aggregates Robinhood and 30+ other brokerages).

Each provider has its own normalizer that maps raw API responses to canonical types (CanonicalAccount, CanonicalHolding).

Key design decisions:

  • costBasis (total invested) and averagePurchasePrice (per unit) are separate fields in CanonicalHolding to handle high-priced stocks like BRK.A correctly.
  • HTTP retry with exponential backoff (1s, 2s, 4s) for 429/5xx responses.
  • Coinbase balance.amount is always 0 in their API; actual balance is available + hold.

MCP Tools (5)

  • list_providers — returns configured providers and capabilities
  • list_accounts — returns accounts (optional provider filter)
  • list_holdings — returns holdings for an account (requires accountId)
  • get_quote — returns current price (requires provider + symbol)
  • get_provider_health — health check for each configured provider

Out of scope (Phase 1): transactions, trading, withdrawals. This is read-only by design.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
